MARIA A. AROSTEGUI, OF MATANZAS, CUBA PIANO PEDAL Application filed July 9, 1930. Serial No. 466,843.

This invention relates to piano pedals, and but the pedal 6 is mounted so that it may more particularly to means for facilitating swing laterally to a limited extent and also the use of the pedal for sustaining the notes. rock vertically. Thus, a metal yoke 1 is In carrying out the invention, I mount the centrally pivoted on a stud 2 in the pedal- 5 sustaining pedal 9. little lower than the soft boX, and this yoke has upstanding arms in pedal and provide the latter with projections which pintles on the sides of the pedal 5 are which extend laterally to guide the foot of pivoted, as shown. The yoke, carrying the the operator easily and surely from one pedal pedal, may swing horizontally about the stud to the other. I also mount the sustaining 2 as an axis, and the pedal may rockvertieal- 1 pedal so that it can swing to a limited extent ly on its pintles. A catch 3 is secured to horizontally, and I provide a catch for lockthefront of' the pedal-box atthe left of the ing the sustaining pedal in its depressed posipedal 6, this catch consisting of a metal strip tion, when desired. The arrangement is such having a shoulder 3 which projects toward that the operators left foot, pivoting on the the pedal. If the pedal 6 is. depressed and 15 heel and extending normally over the soft then swung to the left, as indicated in dotted pedal, may swing surely and easily on to the lines in Fig. 3, the side of the pedal will pass sustaining pedal, and upon depression of the under the shoulder on the catch and the pedal latter a reverse swinging movement of the will be lockedin its lowered position until foot will carry the sustaining pedal laterally moved to the right, when it will spring up- 20 under thecatch so that this pedal will remain wardly into the full line position, shown in depressed after the operators foot has been said figure. returned to its normal position over the soft The pedal 7;, as will be seen in Figs. 1. and pedal.

7 Very commonly, the use of the sustaining pedals of pianos is neglected because of the diflieulty of shifting the foot from its as- 10 signed pedal on to the sustaining pedal, and

because the sustaining pedal is not usuall provided with means whereby it can be read ily locked and released, so as to leave the foot free to operate its assigned pedal. By means of my improvements, it will be evident that the sustaining edal can be readily locked and released and t is leavesthe operators foot free to 0 erate its assigned pedal.

What claim is:

1. In a piano, a soft pedal and a sustaining pedal arranged side by side, the soft pedal pivoted to rock vertically, a yoke in which the sustaining pedal is pivoted for vertical movement, said yoke being swiveled to permit the sustaining pedal to swing horizontally and a catch, at the side of the sustaining pedal, adapted to lock the latter pedal when it is depressed and moved to one side of its normal position.

2. In a piano, a soft pedal, a sustaining pedal mounted lower than and adjacent to the soft pedal, said soft pedal havin a lateral extension for guiding the foot 0 the operator from the latter pedal to the sustaining pedal.

' 3. In a piano, a soft pedal and a sustaining pedal arranged side by side, a catch adjacent the latter pedal, said pedals pivoted to rock vertically and said sustaining pedal being pivoted to permit of horizontal swinging movement toward and from the soft pedal, and adapted to engage under said catch when depressed and moved toward the soft pedal.

4. In a piano, a soft pedal having two lateral extensions, spaced apart, and extending downwardl a sustaining pedal adjacent to and belowt e soft pedal, said sustaining pedal being movable in a horizontal plane, and a catch adapted to lock the sustaining pedal when the latter is depressed and moved toward the soft pedal.
